About

Binary JAR file downloads of the JDBC driver are available here
and the current version with Maven Repository.
Because Java is platform neutral, it is a simple process of just
downloading the appropriate JAR file and dropping it into your
classpath. Source versions are also available here for recent
driver versions. Prior to the 8.0 release the JDBC driver was
distributed with the server source code.

Current Version

This is the current version of the driver. Unless you have unusual
requirements (running old applications or JVMs), this is the driver
you should be using. It supports Postgresql 7.2 or newer and
requires a 1.6 or newer JVM. It contains support for SSL and the
javax.sql package. If you are using the 1.6 then you should use the
JDBC4 version. If you are using 1.7 or 1.8 then you should use the
JDBC41 version. If you are using a java version older than 1.6 then
you will need to use a JDBC3 version of the driver, which will by
necessity not be current
